we know that \[\log_A B+\log_A C=\log_A (B\times C)\] could you use this to simplify?

@mendeaar002 for future reference, could you mention what kind of problem it is in the post at least? like write "another logarith problem" you tend to get better responses that way, though @ash2326 's is perfectly good. I will edit your post for you...
